UNITED STATES MICHAEL V. VENTRELLA, 0F BRGNX, NEW YORK.

AUTOMATIC MUSIC-SHEET TURNER.

Application filed May 29, 1925.

This application is directed to the same subject matter as my co-pendingapplication, Serial Number 33,618, filed May 29, 1925 for automatic leafturner.

This invention relates to improvements in music leaf turners,particularly turners for the leaves of sheet music and it is theprincipal object of the invention to provide a device of this characterin which a cam controlled and foot operated finger engages specialpockets attached to the music sheets while a spring carries the fingerback into its original position, thus taking the sheet of music, thepocket of which is engaged by said finger, along to turn the sheet.

Another object of the invention is the provision of a novel means forattaching the pocket carrying frame to the sheet of music.

A further object of the invention is the provision of a sheet music leafturner provided with means for making its operation positivelynoiseless.

A still further object of the invention is the provision of a sheetmusic leaf turner allowing an adjustment to the size of sheet and to therequirements for operating the pocket engaging finger.

These and other objects of my invention will become more fully apparentas the description thereof proceeds, and will then be more specificallydefined in the appended claims.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a front view of a music stand equipped with a leaf turnerconstructed according to my invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is an enlarged detail view of the cam housing and drum therein towhich a finger adapted to turn the leaves is attached.

sheets and means for attaching the same to said sheets.

The leaf turner is mounted on the customary hollow music stand 10 havingcollapsible legs 11 and foldable links 12 connected to the legs and to asliding collar 13 on the stand.

A rod 14 is vertically displaceable within stand 10 and adapted to beheld in any of its extended positions from said stand by means of theusual wingscrew 15.

This rod 14 carries the customary foldable table or support 16 for thesheets of music 17 supported at their lower ends on the customaryprojecting flange 18.

All these parts so far described, are of ordinary well knownconstruction and form no part of this invention.

In rear of the support the rod 14 carries a plate 19 having elongatednotches 20 in its upper edge and openings 21, 22 and 23 with elongatedslots formed therewith for the reception of suitable buttons 24, 25 and26, or the like, on the support adapted to slide into the elongatedslots for firmly holding said plate 19 on the support.

Similar buttons 27, or the like, of an upper holder 28 enter the notches20 to hold the same in its relative adjusted position to the plate 19.The. holder has a forwardly projecting flange 29 on which rest the loweredges of a card-board or the like frame in cluding, bars 30, foldable inthe center part, one for each sheet of music which have their endsformed into sleeves 31 and 32 respectively, through which substantiallyvertically arranged card-board bars or the like, 33, 34 pass, the lowerends of which are attached by means of staples 35, or the like, passedthrough elements 36, and the sheet of music, in order to secure bars and34 to the upper edges of the musicsheets 17.

At the front faces of the frame bars 30, pockets 37 are formed therewithor fastened thereto by means of glue, etc.

These pockets are adapted to be engaged by an operating finger 38jointed as at 39, to a link 40, secured as at 41, to a drum 42 within ahousing 43 having an opening formed with a cam face 44. Within the druma spiral spring 45 is provided having one of its ends secured to acentral pin 46 while its other end is attached to a boss of the drum. Aspring 47 has one of its ends guided about part 40 and the otherengaging the top edge of operating finger 38. A cable 48 is guided aboutthe drum L2 and secured thereto at one end, at l9, and is guided over aroller 50 in an opening of the housing and a roller journaled in anose52 of plate 19.

To the lows end oi? said cable the upper end of a cable or chain issecured, adapted to be shortened and lengthened as indicated at anhaving its lower end connected to an. operating rod secured to an eye 5?of a tiea le or pedal 5? Weighted as at and having its rear end pivotedto a frame padded as at 60, While a similar pad (51 is attacaed to thelower face oi the pedal oppositely disposed to pad 60 in order to maizethe operation of the foot pedal noiseless. The frame 59 has a U- shapedfront part limiting the upward movement or" the peoal.

The WGlQl'lt 58 is for the purpose of real;- the \ve' it of foot pedal57 to equalize the stren th o1 s1 ring allow finger 38 ant the musicsheet to st in any desired position.

The device operates as l olloivsz Upon the proper adjustment of thechain and 54; to suit the height of the music stand, the pedal isdepressed on the front portion to operate the drum which will swingfinger the link 4C0 to which it is attached guides along the face inposition above the pocket or. It now the pedal is depressed on the rearportion, the spring 45 will act to carry the linger back into itsoriginal position While its link is gliding along the cam face i lto thelower part thereof, allowing the. finger 38 to engage in the pocket 37and carry the music sheet with the pocket which it engaged, into thisposition.

It is to be understood that although I have referred to music sheetsbook pages or any other sheets may be turned by my device. Pcc 'ets 3?oi appropriate may be readily attached to a sheet of correspond in sizeby the musician or any one who to use the sheet turner.

"Ell
